### Cherry Trail IPC3

Topology2 describes the source format and does not require the target firmware
to use IPC4. Cherry Trail firmware uses IPC3, so its targets are built with a
separate IPC3 ABI manifest and installed under `target/sof-tplg` instead of the
IPC4/ACE topology directory.

The Yoga Book topology can be built directly with:

```bash
cmake --build . --target topology2_prod_ipc3_sof-cht-rt5677
python3 ../tools/topology/topology2/verify-cht-rt5677.py \
topology/topology2/production/ipc3/sof-cht-rt5677.tplg
```

`sof-cht-rt5677.tplg` configures SSP2 for DSP_B with an inverted bit clock and
non-inverted frame clock, 48 kHz stereo S24_LE, four 25-bit TDM slots, a
4.8 MHz bit clock, and a 19.2 MHz codec MCLK. These values must stay aligned
with the Linux `cht-yogabook` machine driver. The verifier parses the compiled
artifact and rejects changes to the SSP link or the PCM0/PCM1 stereo contract.

Development and testing topologies go in `development/tplg-targets.cmake`.
